IMPROVEMENT IN SPEEDERS.

Specification forming part of Letters Patent No. 165,352., dated July 6,1875 application filed July 18, 1814.

To all whom it may concern .Be it known that I, THOMAS ll/IAYOR, of thecity and county of Providence, State of Rhode U Island, have invented anew and useful Improvement in Speeders for Spinning and l TwistingRoving; and I do hereby declare that the following is a full, clear, andexact description thereof, which, with the accompanying drawings,forming part of this specification, will enable others skilled in theart to make and use the same.

by brackets from a vertically-reciprocating rack operated by a pinion inthe body of the frame. In such machines serious difficulties exist, andto obviate them is the object of my invention. I

When, in a speeder, the bobbins are completed and ready to be doffed,the machine is stopped automatically by the slide raising the arm M, soas to disengage the pawl at its lower end and allow the weight H to actupon the shifting-rod G through the lever I, by which means thedrivingbelt is placed upon the loose pulley. When, however, the operatorfinds it necessary to stop the machine for the purpose of winding backor changing the relative speed of the different parts, or to mend brokenends, it has heretofore been necessary in most cases to pass along thefront of the machine, and, going behind the same, raise the Weight H andtrip the arm M, and thus allow the weight H to act upon the shifting-rodGr, after which the operator had to return to the front of the machine.loss of time and exertion I place on top of the frame the lever K, sothat the same may be easily reached by the operator from the front ofthe machine-frame. This lever I connect with the armM bymeans of achain, strap, or flexible rod, so that the operator may, by

pulling down the lever K, raise the arm M, l

and so allow the weight H to act upon the shifting-rod G, and thus stopthe machine without going behind the same, thus saving a large amount ofvaluable time and the extra exertion of the operative.

By means of the counter-weights O G the weight of the reciprocatingstep-rail A, with all the weight of the spindles and bobbins supportedby the same, is balanced. This whole weight, being very considerable inlarge frames, has heretofore been supported by brackets projecting fromthe reciprocating rack E, causing considerable friction against thesidesof the vertical slides in which the rack movesyand, consequently, lossof power. The great weight sustained all on one side, and some distancefrom the rack, makes the same bind and wear forward on the upper, andrearward on the lower, end. of the rack and slides, and this wear soonthrows the step ofthe spindle out of its true line, thus not onlyincreasing the friction, but' destroying the true operation of thespindle. To obviate all this I secure to the rail F two or more bracketssupporting loose sheaves O, and also sheaves P on the rear to the frameof the speeder, and to the step-rail A I secure a chain, Wire, rope, orband, and pass the same over the sheaves O and P, and secure the otherend to the weight 0, which is made so heavy as to completely balance thestep-rail A and its appendages, so that no weight shall bear the rackagainst the slides, but the reciprocating motion shall be free and easywithout any unnecessary friction and loss of power.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the shifting-rod e,

the weighted lever I, and the arm M, of the lever K, connected by achain or its equivalent with the arm M, so that by moving the lever K inthe'proper direction the arm M is raised and the speeder stopped,substantially as and for the purpose specified.
